3DM® 2 Online Help

Informing the Operating System of Changed Configuration
After you change the configuration of a unit, you must inform the operating system of the change, and you may need to re-partition the unit.
In addition, in order to use the new capacity, you need to either resize the existing partition or add a new partition.
To inform the operating system that a unit has been changed

1 | If the unit you reconfigured is the boot unit, restart the system and skip to Step 3.

If the unit you reconfigured is secondary storage, unmount the file system from the unit.
Under Windows, go to Start > Administrative Tools > Computer Management, and select Disk Management. Remove the logical drive letter for the unit.
Under Linux, from a command prompt, type sync <enter>, sync <enter>, sync <enter>.
You can then unmount the unit with this command: umount <mount location>

2 | In the software, remove and rescan the controller, in order to update unit information.

a | In 3DM 2 choose Management > Maintenance and select the appropriate unit.

b | Click the Remove Unit button.

c | After the unit has been removed, click the Rescan button. The new unit capacity displays.

3 | Resize the partition and file system or create a new partition.

In Windows, use the disk management utility to determine whether the disk is a basic disk or a dynamic disk.

| Go to Administrative Tools > Computer Management, and then select Disk Management in the list on the left.

Only dynamic disks can be expanded with Windows Disk Management. If the unit is shown as a basic disk, right-click on the disk icon and change it to a dynamic disk.
Older Windows systems cannot convert basic disks into dynamic disks after the file system has been created.

| If the unit is shown as a dynamic disk, right-click on it and choose Extend Volume to launch the Extend Volume wizard.

In Linux, the tools to expand the partition and file system can vary, depending on the kernel version and file system that you are using. Please consult your Linux documentation and the LSI Knowledge Base for more information.
